Abstract
The invention discloses a wear and heat resistant high-chromium glass die. The die utilizes a special melting technology which enables required alloy elements to be commonly melted in an intermediate-frequency electric furnace through a large amount of heat released in a reaction of the alloy elements under a high temperature condition. A special alloy casting which has a good casting performance and is easy to shape is produced through the die. The casting has the advantages of good heat conduction performance, good physical performances, strong wear resistance, strong corrosion resistance and strong oxidation resistance.
Description
Technical field
The present invention relates to a kind of glass mold, particularly a kind of high-chromium wear-resistant thermal glass mould.
Background technology
In recent years, China's glassware glass mold gross output value increases progressively with every annual about 18%, the demand that drives the glass ware mould material increases fast, so far domestic glassware glass mold novel material is in kind, quality, all there is a certain distance the aspect such as dimensions and performance with international most advanced level, particularly the glass mold of glassware is at high temperature produced, differ greatly with the glassware glass mold material of external import, thereby high-grade mould of long lifetime high quality property mould novel material, the product of new variety needs contradiction very outstanding, cause China's annual high-grade glass ware glass mould nearly 50% by import, especially large-scale, accurate, complicated, long-life glassware glass mold Wear-resistant, high-temperature resistant novel material breach is larger.
The circulation of the lot of materials of China's glassware glass mold still is stuck in the primary stage of market economy, and quality can not guarantee fully, improves product specification, replace imported, the high-grade moulding stock of research and development imperative.
Summary of the invention
The purpose of this invention is to provide a kind of heat-resisting, corrosion resistant glass mold.
In order to realize above-mentioned purpose, technical scheme of the present invention is: a kind of high-chromium wear-resistant thermal glass mould, and it comprises the component of following mass percent:
The hardness of described mould is 230-250HB, and shock resistance is 35J/cm
2, tensile strength is 800MPa, Yield strength 700 MPa, and thermal conductivity is counted 30W/m.k, and the friction amount is 3.1% relatively.
Carbon content increases in the steel, and yield-point and tensile strength raise, but plasticity and impact reduction, when carbon amount 0.23% surpassed, the welding property of steel degenerated, and therefore was used for the structural lowalloy steel of welding, and carbon content generally is no more than 0.20%.Carbon amount height also can reduce the atmospheric corrosion resistance ability of steel, and the high carbon steel in stock ground is with regard to easy-to-rust in the open; In addition, carbon can increase cold shortness and the aging sensitivity of steel.
In steelmaking process, add silicon as reductive agent and reductor, so killed steel contains the silicon of 0.15-0.30%.The combination such as silicon and molybdenum, chromium is improved erosion resistance and oxidation resistant effect, can make high temperature steel.The silicon amount increases, and can reduce the welding property of steel.
In steelmaking process, manganese is good reductor and sweetening agent, contains manganese 0.30-0.50% in the general steel.The manganese amount increases, and weakens the resistance to corrosion of steel, reduces welding property.
Chromium can significantly improve intensity, hardness and wear resistance, but reduces simultaneously plasticity and toughness.Chromium can improve again oxidation-resistance and the erosion resistance of steel, thereby is stainless steel, the important alloying element of high temperature steel.
Nickel can improve the intensity of steel, and keeps good plasticity and toughness.Nickel has higher corrosion resistance to soda acid, at high temperature has antirust and temperature capacity.
Molybdenum can make the grain refining of steel, improves hardening capacity and thermostrength, keeps enough intensity and creep resisting abilities (at high temperature be subject to for a long time stress, deform, claim creep) when high temperature.
Copper and its some alloys have preferably corrosion resistance, and are very stable in the air of drying.High intensity, electroconductibility and thermal conductivity are arranged, and processing characteristics, pin weldering property and excellent corrosion resistance can in very large range be controlled its performance by alloying.
Mould of the present invention is produced under 1100 degree high temperature continuously, and every pair of mould can be produced the qualified product more than 600,000 times.
Mould of the present invention has good solidity to corrosion to the aqueous solution of oxidizing acid, most of organic acid and organic salt, on original basis, add again the alloys such as molybdenum, vanadium, copper, at high temperature can keep enough intensity and anti-wear energy, have good processing characteristics and weldability, greatly improved than general material and use on the machine the life-span.
