Embodiment 1

[0026] 1. Production plan:

[0027] To adapt to different raw material sources and carry out different material type design, optimize the steel loading plan for heating furnace according to the characteristics of super stainless steel grades, determine the transition plate with similar width and matching thickness, confirm the plate shape and surface in advance, and produce super stainless steel according to the easy-to-use Strictly limit the production sequence from narrow to wide. For non-standard size blanks, the method of manual positioning and loading of steel is adopted to ensure accurate cloth position and stable loading of steel.

[0028] 2# Heating Furnace Single Furnace: High temperature heating roll stage → coil rolling 2 row transition thickness 8-10mm (within width 2200mm, high strength 960, etc. priority) → wide and thin S32053 alloy coil

[0029] 2. Requirements for the use of blanks:

Abstract

The invention discloses a production controlling method of a wide-width and thin-gauge super stainless steel plate or coil of a single frame steckel mill. According to the significant differences in heating, rolling, crimping, shearing and cutting and straightening processes and the like between the production of the wide-width and thin-gauge super stainless steel plate or coil and the productionprocess of conventional steel, detailed management and controlling are carried out, and the comprehensive pass rate of the wide-width and thin-gauge super stainless steel plate or coil is improved.

Description

technical field [0001] The invention relates to a production control process of a special alloy plate (coil). Background technique [0002] Special alloy plates (coils) such as industrial pure titanium, stainless steel, and nickel-based alloys are usually used in special environments such as biomedicine, nuclear power engineering, chemical containers, and seawater desalination. The production of products is of great significance and has high added value. With the development of the special alloy plate (coil) industry, the demand for wide and thin specifications in the international and domestic markets is gradually increasing, but there are few companies at home and abroad that can produce products with a width greater than 2000mm. The thickness and width of the special alloy plate (coil) produced by the current hot-rolled single sheet can no longer meet the needs of the market. Contents of the invention [0003] The present invention mainly aims at the significant differ...
