Since the beginning of the 1990s, tile shafts have accelerated the development of supporting bearings in the steel industry. The first domestically produced finishing rolling mill bearing for Baosteel 2050 rolling mill successfully passed the national acceptance; independently developed hot rolling 1250 line and hot rolling 1450 line supporting products, one-and two-fold continuous online two-year operation No fault; the independent innovation of Angang's hot-rolled 1580 products, to achieve the entire line to replace imports, the service life of more than two and a half years. At present, the oversized large-scale steel bearings produced by the adobe-shafts have been connected from one point to another, covering the entire surface of the iron and steel industry. These include: split-aligning spherical roller bearings for steel-eared furnaces and ladle turrets. Bearings, hot-rolled sheet, plate, cold-rolled, steel tube mill bearings, H-beam bearings, steel roll turning table bearings, coiler bearings, reducer bearings and so on.
In the fierce competition in the global steel bearing market, the market share competition is the competition of technical strength. Wazhou Group uses quality to improve customer satisfaction and takes new products to seize new markets, leading the industry. Taking the extremely large four-row tapered roller bearings of the steel industry as an example, the tile shaft products have begun to shift from the most original structure to a new structure, making the product more stable. The special four-row cylindrical roller bearings for hot rolling, and the four-row cylindrical roller bearings for cold rolling, which are not equal to the row clearance, form a stable and exclusive supply situation in the steel industry, and the product advantages have increased the market share.
The design, manufacture and operation performance of the oversized large-scale steel bearing has reached the best state, and it is continuously creating a better production environment, lower maintenance costs and higher profits for customers.
Adhesive door frame edges need to be selected according to the material, generally you can use instant glue, slow-dry glue, nail-free glue, UV shadowless glue, swelling glue, etc.
When repairing viscose, to avoid applying glue on a large area, you only need to divide the door frame into four equal parts, and point five points. The two ends and the middle must be glued, and then installed Go back and hold it for a few minutes, and after letting go, the door frame edge will not fall off.
Different glues have different effects, and you should choose and use them according to the material and specific conditions of the door frame edge.
The most convenient way is to use instant glue. After the glue is applied, it can stick together immediately, and the effect is relatively good. The effect is very good for metal and plastic parts. But this kind of glue is easier to paint, and it is easy to have white edges around it after a long time.
The filling effect of slow-drying glue is good, and it will not cause white fog, and at the same time, it will not appear embrittlement. The longer it is used, the better the adhesion will be, but the drying will be slower.
In the case of sticking wooden doors, you can use nail-free glue. Before using, clean the surface to ensure that the surface is free of oil and dust, and then use a sealing gun to squeeze out the glue.
UV shadowless glue belongs to two kinds of bonding. It is only effective if it is a transparent part. The bonding strength is also relatively good, and it dries quickly. After this glue is irradiated by ultraviolet rays, the reaction will be strong and the efficiency is very high. .
