Chromium-bronze alloy board for crystallizer and processing technique thereof

Abstract

The invention relates to a chromium-bronze alloy plate material for a crystallizer and a processing method thereof. The chromium-bronze alloy plate material is composed of copper, chromium, and other inevitable contaminating metal elements. The processing method comprises the steps of fusion casting, face milling, saw cutting, heating, hot rolling, flattening, acid washing, defect detecting, shearing and warehousing.

Description

technical field [0001] The invention belongs to the field of nonferrous metal processing, and relates to a chrome-bronze alloy plate for crystallizers and a processing technology. Background technique [0002] With the continuous updating of metallurgical continuous casting technology, the materials of T2, TP2, TAg0.1 for mold plate for slab and square billet continuous casting machine and TU2 for stave have been gradually replaced by high-performance materials such as chrome bronze. As a key infrastructure material, the chrome bronze crystallizer plate must be accelerated in its technical research and development. Therefore, the production technology research and development of LC1840, the representative product of Chalco Luoyang Copper Co., Ltd.'s chrome bronze mold plate, is in line with the current mold material and the update and replacement trend and development direction of stave materials in the future. At present, copper plates such as copper (T2), phosphorus deox...
