Cold saw cutting machine principle: The cutting method of cold saw cutting machine is generally used in cutting machine and sawing machine. The requirement of cutting is to ensure that the steel incision section is not destroyed. Cold saw cutting machine in addition to a few square, round, Angle steel simple section sometimes used with the cross section of the shape of the shear, the majority of steel sawing. Cold saw cutting machine saw cutting can be divided into hot saw cutting and cold saw cutting. Hot sawing has the advantages of rapid post-rolling treatment, compact equipment and low sawing force, so it is widely used. In order to match with the capacity of the rolling mill, a production line is set up with multiple sawing equipment. When the cold saw cutting machine saws, it should calculate the shrinkage amount according to the steel temperature when cutting, so that the length error after cooling is within the allowed range. The task of cold saw cutting machine sawing is fixed length sawing, so many production lines are equipped with fixed length machine and saw machine supporting. In addition to cutting the head and tail with the cold saw cutting machine, attention should also be paid to cutting the defective part and sampling. Cold saw cutting machine sawing should be combined with supply length to achieve the best material, which is also an important means to improve the yield. Steel cooling to strictly implement the cooling system, the correct placement of steel in the cooling position. Cold saw cutting machine is the most important to prevent the production of improper cooling caused by product quality problems. Such as prevent rail cooling too fast hydrogen precipitation too late and produce hydrogen embrittlement. Cold saw cutting machine cold saw cutting and hot saw cutting contrast, generally defined by the temperature of the cutting rolled parts, there are the following types, cold saw cutting machine rolled parts when the temperature is lower than 100℃ for cold cutting. When the temperature of the rolled parts of the cold saw cutting machine is 100 ~ 600℃, it is warm cutting. When the temperature of the rolled parts is higher than 600℃, it is hot cutting. Cold saw cutting machine generally, we will be used to saw the metal saw mill temperature is lower than 300℃ called metal cold saw, will be used to saw the metal saw mill temperature is higher than 600℃ called metal hot saw. Cold saw cutting machine metal hot saw and metal cold saw, the equipment structure is no difference. For square and round steel production lines, cold sawing machine is seldom used for cold sawing, because the steel is too hard, the sawing area is large, the sawing period is long, and the incision quality is low. Hot sawing or grinding wheel saw is mostly used. Cold saw cutting machine for groove Angle, steel pipe and other production lines, because of its thin wall structure, sawing area per unit time is small, easy to make steel deformation, and serious...

A machine for reeling mulberry silk or tussah silk. According to the degree of mechanization and automation of silk reeling, there are sitting reeling machine, vertical reeling machine and automatic silk reeling machine. The automatic silk reeling machine is divided according to the perception method, there are fixed fiber automatic silk reeling machine and fixed grain automatic silk reeling machine. According to whether there is silk reeling soup, there are water reeling machines and dry silk reeling machines. Recently, vertical reeling machines and fixed-fiber automatic silk reeling machines are widely used. Vertical reeling machine Also known as multiple reeling machines. Named because of the standing operation of the workers. It is mainly composed of automatic threading mechanism, silk reeling table, rotary thread connector, thread collector, silk sheath device, interlacing device, thread coiling device, small paper raw silk drying device, stopping device and transmission device. Each silkworm cocoon standing reeling machine has 20 threads, and each tussah cocoon standing reeling machine has 18 threads, usually each person takes care of one machine. The temperature of the silk reeling soup is about 40°C, and the winding speed is about 50m min. The production efficiency is low, and it has been gradually replaced by automatic silk reeling machines. However, the raw silk reeled by the vertical reeling machine has a good feel and soft silk quality, and is often used to reel a small amount of high-grade raw silk. Fixed fiber automatic reeling machine At present, the silk reeling machine is widely used at home and abroad. The main components are: distance sensor, exploration mechanism, thread adding system, cocoon feeding mechanism, silk reeling trough, thread catcher, thread collector, silk sheath device, interlacing device, small sign coiling device, small plan raw silk Drying device, stopping device and transmission device, automatic Sorris mechanism, catcher for automatically catching cocoons and lining of pupa, and cocoon separation device for automatically separating cocoons and lining of pupa, etc. The linear density (fineness) of the raw silk is indirectly sensed by sensing the diameter of the reeled raw silk through the sensor. When the linear density is lower than the allowable range, a signal for adding threading is sent. The mechanism and the thread catcher can automatically add threads and automatically control the thread density of the reeling silk. The output per unit is more than double that of the vertical reeling machine, usually 20 units per group and 20 threads per unit. Fixed grain automatic reeling machine The first-generation automatic silk reeling machine developed by Japan in the 1950s to indirectly control the linear density of raw silk by automatically controlling the number of fixed grains. Since the grain size sensor is often inaccurate in grain size due to factors such as mechanical failure, cocoon cooking state, and c...

Continuous casters can be classified in many forms. According to the structure and shape, the continuous caster can be divided into vertical continuous caster, vertical bending continuous caster, arc continuous caster with straight line segment, arc continuous caster, multi-radius oval continuous caster and horizontal continuous caster. With the development of continuous casting technology, the research of wheel caster, especially thin slab caster has been carried out. According to the size and shape of the sections cast by the continuous caster, the continuous caster can be divided into slab caster, billet caster, square slab caster, round slab caster, special-section caster and thin slab caster. The billet continuous caster also includes rectangular billet continuous caster. Generally, the billet with cast section or equivalent section area greater than 200×200mm is called generous billet, the billet with section or equivalent section area less than 160×160mm is called small billet, and the rectangular billet with width to thickness ratio greater than 3 is called slab. If the number of billet flows that can be cast by the continuous caster under the same ladle can be distinguished, it can be divided into single flow, double flow or multi-flow continuous caster.
