  • Publication number: 20210047706
    Abstract: Disclosed is a manufacturing method for a high silicon grain oriented electrical steel sheet, the silicon content of the high silicon grain oriented electrical steel is greater than 4 wt %, comprising the steps of: (1) performing decarburization annealing of a cold-rolled steel plate; (2) allowing high silicon alloy particles in a completely solid state to collide at a high speed with the surface of the decarburization annealed steel plate to be sprayed, thus forming a high silicon alloy coating on the surface of the steel plate to be sprayed; (3) coating a release agent and drying; and (4) annealing. The manufacturing method for the high silicon grain oriented electrical steel sheet of the present invention is inexpensive, and, the high silicon grain oriented electrical steel sheet produced is of stable quality and is provided with great magnetic performance.

  • Publication number: 20200291501
    Abstract: An apparatus and a method for rapidly heating cold-rolled strip steel (10). The apparatus for rapidly heating cold-rolled strip steel (10) comprises a heating zone, a soaking zone, and a cooling zone, and the heating zone is sequentially divided into a first heating section (1), a second heating section (2), a third heating section (3), and a fourth heating section (4) along a moving direction of the strip steel (10) to be heated, the first heating section (1) and the fourth heating section (4) being radiant heating sections, and the second heating section (2) and the third heating section (3) being inductive heating sections. The method for rapidly heating cold-rolled strip steel (10) uses the apparatus for rapidly heating cold-rolled strip steel (10) to heat the strip steel (10).

  • Publication number: 20150041688
    Abstract: An electro-hydraulic system for driving a large-scale rotary motion valve supplied by a solar low-capacity power. A step motor (2) and an oil pump (3) are in turn driven by a low-capacity solar power supply (1). An oil tank (5), the oil pump, a check valve (6), a T-connector (7) and a liquid accumulator (10) are in turn arranged on an oil storage pipeline (4). An oil inlet pipeline (16) is connected to the rest of the ports of the T-connector. An oil inlet of a three-position four-way reversing solenoid valve (12) is connected to the oil inlet pipeline. Two ends of an oil return pipeline are connected to an oil return port of the reversing valve and an oil return port of the oil tank, respectively. Each of two oil outlets of the reversing valve is respectively connected to an oil port of a single-chamber cylinder via a pipeline. The outer ends of the piston rods of cylinders A and B are rigidly connected together to form one piston rod (134).
