Casting process of high-manganese steel lining plate used in as-cast state

Abstract

The invention discloses a casting process of a high-manganese steel lining plate for as-cast use, and relates to the technical field of casting, and the casting process comprises the following steps: step 1, preparing furnace charge for as-cast use; 2, smelting the high-manganese steel lining plate; step 3, casting process design; and 4, heat treatment, cutting and welding. Through the arrangement of the placement assembly, the inner pool and the outer pool, the anti-splashing effect is achieved, water flows into an overflow ring groove through a guide cambered surface, water is collected, the situation that the water falls onto the ground and consequently workers slip is prevented, the safety of the working environment is improved, and the working efficiency is improved. Through furnace charge used in a casting state, smelting of the high-manganese steel lining plate, casting process design, heat treatment, cutting and welding, casting process optimization and determination of key casting parameters and product quality standards, key control points can be quickly grasped in the casting process of the high-manganese steel lining plate, efficient and stable casting of the high-manganese steel lining plate is facilitated, and the casting quality of the high-manganese steel lining plate is improved. And convenience is brought to operation.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a casting process of a high manganese steel liner used in the cast state. Background technique [0002] High manganese steel liners are divided into 5 grades according to national standards, the main difference is the carbon content, which ranges from 0.75% to 1.45%. High impact and low carbon content. The manganese content is between 11.0%-14.0%, generally not less than 13%. There is no national standard for ultra-high manganese steel lining, but the manganese content should be greater than 18%. The level of silicon content has a great influence on the impact toughness, so the lower limit should be taken, preferably no more than 0.5%. Low phosphorus and low sulfur are the most basic requirements. Since the high manganese content naturally plays a role in desulfurization, phosphorus reduction is the most important thing. Try to keep phosphorus below 0.07%. Chromium improves w...

Problems solved by technology

[0005] The present invention provides a casting process for high manganese steel liners used in the as-cast state. One of the purposes is to prevent water splashes during quenching, and to solve the problem that commonly used quenching devices often fall into water from a high altitude and easily cause water splashes. It leads to humidity in the environment, which is likely to cause the staff to slip and fall; another purpose is to solve the casting process of the high manganese steel lining plate used in the general cast state, which often fails to grasp the key points, which affects the high manganese steel lining. The problem of plate casting quality enables the casting process of high manganese steel lining plate to quickly grasp the key control points, which helps the casting of high manganese steel lining plate to be carried out efficiently and stably, and brings convenient effects to the operation
