一、问题的提出树脂瓦在三辊劳特式轧机使用较普遍(见图1),但是,近年来由于树脂瓦质量欠佳,使用上也少有改进,因此,中板厂的树脂瓦消耗量有所增加。1982年第一季度使用量已达到上半年的总耗量,平均每月40多片,生产当中停车换瓦的时间长达13.4h,直接威胁着产品产量、质量及成材率的提高。 First, the issue put forward Resin tile in the use of three-roll Lott mill is more common (see Figure 1), however, in recent years because of the poor quality of resin tiles, there are few improvements in use, therefore, the plate mill resin tile consumption The amount has increased. In the first quarter of 1982, the amount of usage has reached the first half of the total consumption, an average of more than 40 pieces per month, the production of parking shredding for a long time up to 13.4h, a direct threat to product yield, quality and yield improvement.
