Description
Technical field
The present invention relates to the deep processing of non-metallic material, is a kind of natural wollastonite heating and melting to be made the method for molten silicon lime stone, and product is mainly used in industries such as metallurgical and welding electrode.The continuous casting covering slag of scouring agent and pouring molten steel outside metallurgy industry can be used as the stove of purification of molten steel; In the welding electrode industry, can be used as coating of welding electrode.
Background technology
Natural wollastonite heating and melting being prepared the method for molten silicon lime stone, all belong to the initiative technology at home and abroad, is the new technology by contriver's research, exploitation.At present, except that the product that the technology of the present invention is produced, the wollastonite of other industrial raw material synthetic of a small amount of usefulness is still arranged on the market, and aspects such as the technology of the present invention workinprocess cost, output capacity and fusion effect has special advantages than the synthetic technology.
Summary of the invention
Wollastonite is a kind of nonmetallic minerals that extensively is present in occurring in nature, owing to be subjected to the restriction mutually of its place of production, structure and thing, chemical ingredients instability, physicals also have very big variation, can not satisfy metallurgy and wait some industry higher requirement.The present invention is a base-material with the natural wollastonite of certain component, according to the composition requirement of variant production, after other auxiliary materials mix, heating and melting together, variation has all taken place in its chemical ingredients and physical properties on request, and chemical constitution has reached the ideal value of design, and character is more stable; The change of thing phase makes the use properties of product that the essence variation take place, and has improved and improved the comprehensive result of use of product.
The present invention is base-material according to the requirement of purpose product to its moiety with natural wollastonite, suitably adds a small amount of other auxiliary materials and carries out heating and melting.Composition of raw materials is:
Material name component concentration % weight percent
Base-material: natural wollastonite CaSiO
