Abstract
The present invention provides a producing method of tungsten, molybdenum and alloy products thereof, which relates to a producing method of tungsten, molybdenum and alloy products thereof used for a quartz glass industry and various crystal material industries. The present invention is researched for solving the problems of lager equipment investment, high powder consumption, small product density, poor safety, etc. of the existing mehtods for producing the products. In the present invention, tungsten, molybdenum and blank work pieces thereof are put into a vacuum graphite heating furnace; then vacuum pumping is carried out after the graphite heating furnace is sealed; heating the graphite heating furnace to a required sintering temperature by power transmission; finally the temperature is lowered, and the tungsten, molybdenum and blank work pieces thereof are taken out after being sintered. The present invention has the advantages of small equipment investment, little power consumption for production, large product density, low production cost and high safety performance.
Description
Technical field: the present invention relates to a kind of tungsten, molybdenum and the molybdenum alloy of silica glass industry and various crystalline material industries, production method of miramint goods of being used for.
Background technology: silica glass industry and used tungsten, molybdenum and molybdenum alloy, the miramint goods of various crystalline material industry mainly are to produce with hydrogen shield Medium Frequency Induction Heating Furnace or vacuum resistance process furnace at present.The former process furnace will be made heating element with tungsten or Mo, and makes thermal insulation layer with lagging materials such as zirconium white and aluminum oxide, and facility investment is big, and power consumption is many, and product density is little, hydrogen explosive, poor stability; The latter also will make thermoscreen with tungsten plate, molybdenum plate etc. and make thermal insulation layer except that doing the heating element with tungsten or Mo, and shortcoming is that facility investment is excessive, the production cost height, and equipment life is low, and maintenance cost is big.
Summary of the invention: the purpose of this invention is to provide a kind of production method that can overcome tungsten, molybdenum and the alloy product thereof of above-mentioned two kinds of production method shortcomings.
The object of the present invention is achieved like this: the blank workpiece of tungsten, molybdenum and alloy thereof is put into graphite material makes heating element, materials such as graphite felt and carbon felt are done to carry out sintering in the vacuum graphite heater furnace of thermal insulation layer.Advantage is that facility investment is few, and power consumption is few during production, and product density is big, and production cost is low and safety performance good.
Embodiment: tungsten, molybdenum and molybdenum alloy, miramint blank workpiece are put into graphite material and make heating element, materials such as graphite felt and carbon felt are done in the vacuum graphite heater furnace of thermal insulation layer, vacuumize after the sealing, send electrically heated to required sintering temperature, keep certain hour, burn till the back cooling and come out of the stove.
Claims (1)
1, the production method of a kind of tungsten, molybdenum product is characterized in that tungsten, molybdenum blank workpiece are put in the vacuum graphite heater furnace, vacuumizes after the sealing, send electrically heated to required sintering temperature, burns till the back cooling and comes out of the stove.
