Title: Manufacture of stainless clad steel plate
Inventor: SOGOU YASUO
IPC: C21D8/02
Filed: 1982-02-19
Abstract: PURPOSE: To manufacture the titled as-rolled steel plate at a low cost without injuring its corrosion resistance, by using the base plate of low-carbon steel having carbon content and carbon eq. lower than those of stainless steel as a cladding plate, and acceleratively cooling the clad steel plate with the ratio of the volume of water in response to a clad ratio after hot-rolling it.  
     CONSTITUTION: The base plate of carbon steel having carbon content lower than that of stainless steel as a cladding plate and the composition whose carbon  eq.= C+Si/24+Mn/6 is in the range of 0.2W0.35 is put on said stainless steel.  Thereafter, the layered materials are heated above 1,000°C and hot-rolled. In  succession, the clad plate is acceleratively cooled with the density of the volume  of water of 0.3W4.0m 3 /min in a manner such that the volumes of water from the upper and lower surfaces are controlled at such the ratio to countervail the differences in thermal expansion and sectional area between the sides of the  base plate and the cladding plate. Consequently, the deformation of the clad steel plate is substantially eliminated.
