Description

technical field [0001] The invention relates to the field of stainless steel strips, in particular to a working method of a protective guide device for steel strip cold rolling. Background technique [0002] Like other materials, the physical properties of stainless steel strip mainly include the following aspects: thermodynamic properties such as melting point, specific heat capacity, thermal conductivity and linear expansion coefficient, electromagnetic properties such as resistivity, electrical conductivity and magnetic permeability, and Young's modulus of elasticity , rigidity coefficient and other mechanical properties. These properties are generally considered to be the inherent characteristics of stainless steel materials, but they are also affected by factors such as temperature, processing degree and magnetic field strength. Under normal circumstances, compared with pure iron, stainless steel has lower thermal conductivity and higher electrical resistance, while pr...

Problems solved by technology

[0007]1. The protective brush before cold rolling is of fixed design. It only uses the friction force generated by the steel belt and the brush to clean foreign matter, and there is no brushing action designed , it is inconvenient to clean up foreign matter with strong adhesion on the surface of the steel strip. At the same time, there is no designed collection structure. The foreign matter will adhere to the brush and cannot be discharged in time. Instead, it will damage the surface of the steel strip that will be transported later. In turn affect the quality of the steel strip

[0008]2. The guide wheels are embedded inside the device through the fixing mechanism. When it is damaged, it is inconvenient to disassemble and assemble, and the two guide wheels should be adjusted according to the width of the steel belt. When the spacing is large, there are many steps, a lot of time is wasted, and the practicability needs to be improved.

[0009]3. Use the cooling sponge to dip in water to cool down the surface of the cold-rolled steel strip. The water consumption is fast, and water resources need to be replaced frequently, which is easy to cause waste, so it is not necessary It is beneficial to reduce costs, and at the same time, water cooling is used to cool down, and the cooling effect needs to be improved
