Problems solved by technology

[0003] When casting is in progress, it is completed through wax pattern making, wax welding, dewaxing, roasting, melting, pouring, cleaning and post-processing. In casting, the standard operation of any link is to prepare subsequent high-quality precision castings The smelting stage is the most critical, which is to ensure the liquefaction of metal materials. It is usually carried out in the furnace. Due to the characteristics of the furnace, in actual operation, the inner wall of the furnace must be added and used accordingly. Therefore, in order

Abstract

The invention discloses a precision casting smelting furnace lining material and relates to the technical field of precision casting. The precision casting smelting furnace lining material is prepared from the following raw materials: 60-80 parts of quartz sand, 20-30 parts of quartz powder, 6-8 parts of boric acid, 1-3 parts of water glass, 10-20 parts of refractory mortar, 3-5 parts of silicon carbide, 1-3 parts of chromium concentrate, 2-4 parts of ceramic fiber, 3-5 parts of mineral fiber and an appropriate amount of water. The invention has the following beneficial effects: the design is novel; the adopted formula of raw materials is scientific and reasonable; sufficient matching of the raw materials is ensured; the prepared furnace lining material has an excellent performance, is fire-proof and wear-resistant and realizes a remarkable using effect; meanwhile, in moulding, through multi-layer processing, the fastening property of the furnace lining is ensured, and the promotion and application are facilitated.

Description

Technical field [0001] The invention relates to the technical field of precision casting, in particular to a method for forming precision casting furnace lining materials and furnace linings. Background technique [0002] Casting is a metal thermal processing technology that humans have mastered relatively early, with a history of about 6000 years. China has entered the heyday of bronze castings between 1700 and 1000 BC, and the craftsmanship has reached a very high level. Casting is a method of pouring liquid metal into a casting cavity suitable for the shape of the part, and after it is cooled and solidified, the part or blank is obtained. [0003] When casting is in progress, it is completed through wax mold making, wax pattern welding, dewaxing, roasting, melting, pouring, cleaning and post-processing. In the casting, the standard operation of any link is the preparation of subsequent high-quality precision castings Among them, the smelting stage is the most critical, which i...
