Botou tianlong casting is one of the problems in the production of the iron well cover. This problem is one of the main causes of the increase of waste products. So what causes this problem? What method can be used to improve this problem? Let's briefly introduce the problem.
The reason for hole cover hole of nodular cast iron manhole cover is that the seal is not strict and the concrete mortar is blocked. Or the external sand is filled with a hole. When inserting a handle hole to open the cover, the wrench cannot be inserted and the lid cannot be opened. The second is the marginal unpronounceable, the welding of the bottom, or the steel plate of the corner handle is too thin. And cover hundreds of pounds with marble or permeable brick, between the lid and impurities, it is difficult to put forward basic coverage will choke cap base, under a variety of forces, marginal DiKong plate can fall off from the manhole covers the whole.
So botou tianlong casting to thickening of the casting, steel plate, stainless steel pressure side and top, so to solve the problem of original welded type manhole cover, and keep in contact with stainless steel cover and beautiful, this is the basic measures of edge horn DiKong always solve the problem.
Introduces the above main reason, botou tianlong casting edge horn of the main causes of nodular cast iron manhole covers are introduced and the solutions, such as the problems in the construction process, you can refer to the above is introduced for processing and maintenance.
