PURPOSE: An inner cover for steel plate thermal process is provided to minimize subsidence deformation when a crane hits the inner cover and reduce processing time by being pulled by a crane. CONSTITUTION: An inner cover(100) for steel plate thermal process comprises a hollow body(150), a top panel board(130), and a reinforcing material(121). A top panel board blocks the top of the body. The reinforcing material is formed inside the top panel board. A plurality of reinforcing materials are arranged at the same angle from the center of the top panel board. A center reinforcement part is formed on the center of the top panel board. |
