When Chongqing stainless steel processing smelting process route different metal materials will be produced using different smelting process uses metal material chrome ore sector, generally as the main raw material in hot metal, chrome ore mainly through a reduction in the converter, providing chromium, reduce steel production costs. It is through the submerged arc furnace smelting chrome ore. Natural water containing ferrochrome. Stainless steel smelting production process of selection depends on many factors stainless steel, the primary factor is the manipulation of the capital, which affected production scale, product mix, raw material supply, the follow-up process, the existing plant status and power supply status. Returns scrap metal material using ordinary scrap or when the electric arc furnace is generally used as the initial furnace steel shelf, melting scrap and alloy materials to produce stainless steel liquor, producing stainless steel. If you want to smelting Cr-Ni system or Cr-Nr-Mo stainless steel, molybdenum also need to configure the electric arc furnace to melt iron and nickel iron. Metal material using water + when scrap sector ferrochrome smelting arc furnace production process can be a two-step EAF-AOD or use a submerged arc furnace EAF-AOD-VOD three-step method. Typical smelting production process is a two-step selection EAF- AOD or VOD selection EAF- AOD a three-step method produces tissue. Stainless steel parts processing technology introduced during drilling drilling stainless steel wine rack, stainless steel due to poor thermal conductivity, elastic modulus is small, it is also more difficult hole machining. Hole solve problems such materials, mainly appropriate choice of tool materials (1) Select the tool material due to the processing of stainless steel parts cutting power, high temperature stainless steel door cutting tool material should try to choose high strength, good thermal conductivity Hard alloys. For the processing of such materials hardened parts can be used CBN inserts, CBN hardness only to diamond, hardness of up to 7000 ~ 8000HV, therefore high wear resistance, as compared with diamond, CBN advantage is high in heat resistance than diamond much more, up to 1200 ℃, can withstand high cutting temperatures. Besides its great chemical inertness, and the iron group metals do not play a role in chemistry at 1200 ~ 1300 ℃, making it ideal for machining stainless steel. Which is several times the tool life of carbide or ceramic cutting tools. (2) tool geometry parameters on the cutting tool geometry plays an important role for the cutting light, smooth, carbide cutting tools should adopt a large rake angle to improve tool life. When general roughing, front corner taken 10 ° ~ 20 °, 15 ° ~ 20 ° take semi-finishing; take 20 ° ~ 30 ° finishing. The selection is based on the main angle when the process system rigidity is good, desirable 30 ° ~ 45 °; if the process system rigidity is poor, then take 60 ~ 75 °, when the ratio of length to diameter of the workpiece more than 10 times, it is desirable 90 °.
