Problems solved by technology

[0003] The present invention provides a method for controlling the coiling tower shape of magnesium oxide coating on silicon steel, which solves the technical problem that the coiling tower shape is prone to occur due to the influence of magnesium oxide coating in the production of silicon steel in the prior art, and prevents the steel coil from becoming scrapped Coil, and to prevent the steel coil from being smoothly removed from the coiler shaft and affecting production

Embodiment Construction

[0028] see figure 1 , in the production of silicon steel, because the coating roller (including the upper coating roller and the lower coating roller) of the coating machine is made of rubber material and is a driven roller, the friction force of the strip steel makes it rotate during use, which may easily cause the wear of the roller body , coupled with strip steel rolling plate problems (such as edge wave and transverse thickness difference), uneven lateral wear of the roll body, and changes in the level of the coating roll with the passage of time, will inevitably lead to the occurrence of uneven coating thickness. Coiled steel coil 1, the thickness deviation accumulates as the coiling diameter of steel coil 1 increases, and a conical coil appears, such as figure 1 shown. In the case of high-tension coiling, there is a transverse component force acting on the steel coil 1; at the same time, during the process of EPC adjusting the edge alignment of the strip steel, the late...

Abstract

The invention relates to the technical field of metallurgy, in particular to a control method for the telescope of a silicon-steel magnesium oxide coating. The control method comprises the steps of calibrating an upper coating roller and a lower coating roller, controlling the level degrees of the upper coating roller and the lower coating roller to within 0.01mm / m; improving the output power of a drying oven nozzle; and controlling the deviation between a steel reel rolling diameter calculated value and a real-time diameter of a steel reel to within 1 / 1000. According to the control method for the telescope of the silicon-steel magnesium oxide coating provided by the invention, the technical problem that the telescope occurs easily due to the influence of the magnesium oxide coating during silicon steel production in the prior art is solved, the steel reel is prevented from becoming a scrap, and the phenomenon that the production is influenced since the steel reel cannot smoothly move out from a mandrel of a reeling machine is avoided.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for controlling the coiling tower shape of a magnesium oxide coating on silicon steel. Background technique [0002] Silicon steel refers to an extremely low-carbon ferrosilicon alloy with a silicon content of 0.5% to 4.5%. It is divided into non-oriented silicon steel and grain-oriented silicon steel due to different structures and uses. Silicon steel is mainly used as the iron core of various motors, generators, compressors, motors and transformers, and is an indispensable raw material product in industries such as electric power and home appliances. In the production of silicon steel, according to the process requirements, the strip steel is coated with magnesia coating solution and dried before coiling. Due to the influence of magnesia coating, the coiling tower shape is very easy to occur. The steel coils that are lighter do not meet the material receiving stand...
