Shape carving 10mm-50mm aluminum relief crafts Aluminum relief carving aluminum plate is a kind of metal sculpture that carves a low fluctuation image on the plane. It is an artistic embodiment between round carving and painting. Its spatial structure can use a three-dimensional shape or some plane shape, which can not only be attached to a certain carrier but also exist relatively immediately. The two-dimensional or planarity of aluminum relief sculpture after body tightening treatment. The relief technology used is mainly line, supplemented by surface; Combined with relief, thin relief, and shallow relief. The mature technology of Yin relief, line engraving and hollowing out. The spatial shape of aluminum plate relief sculpture is the so-called compact space between the two-dimensional virtual space possessed by painting and the three-dimensional solid space possessed by round sculpture. The compact space reduces the free development of aluminum plate relief space. With the support of plane scenery, the sense of entity of round sculpture is weakened and adopted more.

Sometimes there will be some defects after this work, which need to be repaired. What should be done with this process?
1. Preparation before welding repair. Carefully recover the defects to be repaired, mark the position, and completely remove all defects. Under the condition of ensuring full penetration, the size of the groove shall be reduced as far as possible, and the welding equipment and welding materials must be prepared and dried.
2. Determine the method of welding. The welding method shall be reasonably selected according to the structure and size of EPC equipment, defects, and whether the processing is required after welding repair.
3. Welding repair process parameters. During arc cold welding, DC reverse connection, short arc and intermittent welding shall be adopted. Under the condition of a good turnout, small current and fast welding shall be adopted, and the temperature of the repair welding area shall generally be lower than 60 ℃.

Casting Method Of Babbitt Bearing Bush
In the maintenance workshop, the worn Babbitt alloy bearing bush is often re-cast with a new lining and then continue to be used. The technological process includes preparation of bottom pad, melting of Babbitt alloy, clamping, casting and inspection of the bottom pad. The working experience of our factory over the years is summarized as follows.
Preparation of Bottom Tile
1. Melt the old Babbitt alloy lining
Clean up the old bearing bush, and then heat the back of the Bush evenly on the carbon furnace. When heated to 250 ~ 300 ℃, the tin coating begins to soften, gently knock down the alloy layer with tools, and then remove the remaining alloy with shovels, scrapers and other tools.
2. Cleaning of bottom tile surface
After removing the alloy layer, check whether the surface of the bottom tile to be tinned is clean. If it is not clean, it will make tinning difficult and the bonding quality between the alloy and the bottom tile is difficult to guarantee. If there is dirt or oxide on the tinned surface of the bottom tile, sand and anti-corrosion zinc rod can be used. There are many kinds of zinc alloys and different classification methods. According to habits and application methods, there are roughly three classification methods.
Classification By Alloy Composition
Zinc alloys can be divided into four categories according to their composition: Zn Al system, Zn Cu system, Zn Pb system, and Zn Pb al system. Zn Al alloys generally contain a small amount of Cu and Mg to improve the hardness and corrosion resistance. Zn Cu alloys generally also contain Ti, also known as Zn Cu Ti alloys. This alloy is a creep-resistant alloy. Sometimes a small amount of Cr is added to further improve the creep resistance. Zn Pb alloys are generally used for punching battery shells and can be made into various hardware and sports equipment.
