1 check before the furnace body and a furnace door, trailers, steel wire rope pulley and a blower is normal, there is no collapse, fracture, cracking and other unsafe factors exist. If any, should be properly handled before start-up. The use of annealing furnace should be carefully cleaned the resistance wire on or near the oxide and metal.

2 fire, to carefully check the explosive in coal. Wind stopped process, shall not be applied in thick coal seam, to prevent gas explosion. Removal of coal cinder to be dealt with at any time, no backlog of stacking.

The 3 loading and unloading, to check the track groove is no obstacle, hook, chain and other tools are reliable.

4 loading and unloading large castings or thin-walled workpiece, must keep pad. Due to the space between adjacent, loading height should not exceed the specified.

5 released before, should clean the oven door refractory bricks, refractory clay, and check whether the use of pulling mechanism.

6 discharging and transporting, irrelevant personnel are not allowed near the flat sides, so as to avoid the sand box or workpiece collapsed. Banned in the furnace body surrounding the rest or piling objects.

7 working temperature is higher than 400 ℃, prohibit the use of chain or rope lifting ( or take measures to avoid the fracture ), after annealing. Use driving hoisting work, should abide by traffic and linked to industrial safety operation rules.

8 use the gas stove, should comply with the gas ignition order : first the compressed air is blown furnace gas, compressed air to valve shut, igniting the ignition rod, its gas burning nozzle nozzle valve, adjust the compressed gas and gas flow, the sufficient combustion. A ceasefire in reverse order, is strictly prohibited in reverse order.

9 with oil furnace baking, firing order is: to close the choke, igniting the ignition rod, its accelerator, point, regulating air valves and throttle to full combustion, ban " pressure oil ".

10 the use of pulverized coal fuel furnace, banned in the blower faulty or pipeline cracks when burning furnace.

11 repair electric must cut off switch, hanging on " someone overhaul, prohibit closing " warning signs, or a person.

Cast iron category: according to national grade classification of gray iron castings ( HT ), labeled HT200\HT2500\HT300, nodular cast iron (QT ), labeled QT450\QT500\QT600\QT700, ductile iron gray iron castings has better wear resistance than the smaller, deformation characteristics, nearly a few on a relatively high quality requirements of castings, already began to use a ball nodular cast iron material.
