托辊网带式可控气氛热处理生产线温控
托辊网带式可控气氛热处理生产线温控、电控以及气氛控制采用了计算机控制技术。实现各温控区(淬火、回火、油槽)加热温度、加热时间以及炉内碳势实时与历史记录的监察、设定、存储、等功能。同时还包含“产品、品种、规格、型号、跟踪号、操作工、数量、班次”。可实现历史数据记录,便于查询、追溯,消除了人为因素带来的不利影响。
The computer control technology is adopted for temperature control, electric control and atmosphere control of the controlled atmosphere. Realize the temperature control zone (hardening, tempering, tank) heating temperature, heating time and furnace carbon potential in real time and historical records of monitoring, Settings, storage, etc. Function. It also contains "product, variety, specification, model, tracking number, operator, quantity, shift". Records of historical data can be made to facilitate inquiry and traceability, eliminating the adverse effects of human factors.
(3)采用了甲醇低温裂解技术
(3) the technique of low temperature cracking of methanol was adopted
长期以来为减少氧化脱碳采用了向炉内直接滴注液体甲醇,通过甲醇燃烧消耗炉内的氧气达到减少脱碳目的。这种方法极易产生大量的炭黑,影响工件表面质量。生产线采用的甲醇低温裂解技术就是采用专门的装置把甲醇低温催化裂解成氢气(H2)和一氧化碳(CO)再通入加热炉内燃烧掉炉内的氧气(O2),再向炉内通入少量的丙烷气体作为副化气,起到保护气氛减少氧化脱碳作用。实产品脱碳层深度控制在0.06mm以内满足了客户要求。
For a long time, the use of liquid methanol in the furnace to reduce oxidation reduction has been used to reduce the reduction of carbon in the combustion furnace. This method produces a large amount of black carbon, which affects the surface quality of the workpiece. Production line using the low temperature methanol cracking technology is to use a special device to methanol at low temperature catalytic pyrolysis into hydrogen (H2) and carbon monoxide (CO) and then pass into the furnace combustion oxygen (O2), burning furnace to furnace ventilation with a small amount of propane gas as deputy gas, protective atmosphere reduce oxidation decarburization effect. The real product decarburizing layer is below 0.06 mm to meet the customer's requirement.
