Description
Technical field
The present invention relates to the plant equipment in general fragmentation, grinding, flotation, pulverizing field, particularly a kind of manufacturing process of composite abrasion-proof stick.
Background technology
Rod mill is widely used in the operations such as fragmentation in the industrial trades such as coal, metallurgy, mine, electric power, building materials, refractory material, the energy, powder process, flotation, grinding.Abrasion-proof stick impacts the grinding charge material in rod mill and grinds, and the abrasion-proof stick surface is produced cutting to abrasive material and cutter is cut effect, so abrasion-proof stick is a topmost wear-out part in the rod mill, the demand in domestic every year is more than 100,000 tons.The used abrasion-proof stick material of every profession and trade mainly contains several single metal material such as potassium steel, multi-element low alloy steel, carbon steel at present.Potassium steel is only under high load capacity, high impact stresses, realize that austenite is to martensitic solid-state phase changes and work hardening, just can give full play to its wearability, and yield strength is low, easily produces plastic flow, and in grinding machine, frotton is to impact mutually indirectly by the abrasive material accumulation horizon, impact strength is less, and drawing hardening effect is not remarkable, so wearability does not reach ideal value; The macrohardness of multi-element low alloy steel because hardness is low, can not be resisted being pressed into and paddling of abrasive material about HRC40, in use the surface produces a large amount of cutting and flow low-cycle fatigue, so wearability is bad; Carbon steel hardness and toughness are also bad to be taken into account, and is difficult to competent abrasion-proof stick and carefully grows wear-resisting again requirement.In recent years, concrete operating mode and resource situation at the abrasion-proof stick wearing and tearing, mainly launch research in aspects such as alloying, Technology for Heating Processing, smelting pouring technology more both at home and abroad in chemical composition, develop multiple high-abrasive material, mainly contain modified high manganese steel, medium managese steel, ultra-high manganese steel series, high, medium and low carbon wear-resisting alloy steel series, but because single material can not take into account various field working conditions at aspect mechanical mechanics properties such as intensity, hardness, plasticity and toughness and have specific (special) requirements, so useful life is still very short or be difficult to satisfy the needs of various operating modes.In addition, above-described alloy wear-resisting rod will consume non-ferrous metals such as a large amount of manganese, chromium, nickel, copper, causes the national strategy resources reserve to reduce.The Chinese patent " rod mill composite abrasion-proof stick " of applicant's application, the patent No. " ZL97239713.2 ", adopt the combination process of reinforcing bar and wear resistant cast iron, performance indications such as the impact resistance of abrasion-proof stick, mar proof are improved and improved, but at different operating modes, also need to further investigate, develop a kind of new composite abrasion-proof stick manufacturing process that is used for rod mill, further improve the serviceability of rod mill from aspects such as material, internal structure, manufacturing process.
