護(hù)坡模具應(yīng)貯存于常溫干燥庫中。堆碼高度不得超過3.5 m,應(yīng)避免重壓或擠壓堆放。
The slope protection mould shall be stored in the normal temperature drying warehouse. The stacking height shall not exceed 3.5m, and heavy pressure or extrusion stacking shall be avoided.
護(hù)坡模具不允許與有毒有害物質(zhì)混放，應(yīng)遠(yuǎn)離熱源，在存放處應(yīng)設(shè)置醒目的禁火標(biāo)志。
The slope protection mould shall not be mixed with toxic and harmful substances, and shall be kept away from the heat source. Striking no fire signs shall be set at the storage place.
護(hù)坡模具制作工藝特性
Manufacturing process characteristics of slope protection mould
1．可鍛性
1. Malleability
具有較低的熱鍛變形抗力，塑性好，鍛造溫度范圍寬，鍛裂冷裂及析出網(wǎng)狀碳化物傾向低。
It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low tendency of forging crack, cold crack and precipitation of network carbide.
2．退火工藝性
2. Annealing process
球化退火溫度范圍寬，退火硬度低且波動范圍小，球化率高。
The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.
3．切削加工性
3. Machinability
切削用量大，刀具損耗低，加工表面粗糙度低。
Large cutting parameters, low tool loss and low machining surface roughness.
