The α single-phase bronze sculpture in temperature brittleness appears in forging

The first is the improvement of the efficiency of plating mirror, splashed plating from the previous manual to automatic control spraying. The coating is uniform, dense, solid silver transformed into a utilization rate of more than 90%, the production rate can reach 10 m / m in. Two silver-plated, add a layer of copper plating to protect the precious silver reflective layer, greatly improving the life of the silver mirror. The bronze represents the enigma of ancient science and technology. Is changed by the manual operation of the paint curtain leaching paint. Paint with lacquer lip lacquer paint pump into the tank, and paint from the lip of the paint evenly shed such as a curtain. Plated silver and copper lenses 70 ~ 80 m / min. Speed, high-speed paint curtain, then topped with a uniform layer of protective paint on the lenses. Another example is the former method by far infrared drying and high-pressure air-cooled, pour the second layer protection paint, and 150 ° C far-infrared drying, air-cooled.
 So that the resulting film is uniformly solid, smooth, feel good, corrosion-resistant, further increase the service life of a silver mirror. Fourth, product specifications, varieties, and the thickness can be from 2 ~ 10 mm, specifications largest up to a dozen square meters. The continuous improvement of quality float glass quality, the quality of the silver mirror can be improved. The processing of a variety of milling, drilling, fountains and other secondary processing, more advanced silver mirror crafts to beautify people's lives. Bronze is an alloy composed of copper and zinc. The research group used modern technology and techniques to examine the bronze. If only composed of copper, zinc, bronze is called the ordinary bronze. By more than two kinds of elements composed of a variety of alloy known as special bronze. Such as lead, tin, manganese, nickel, lead, iron, silicon, copper alloy. Bronze have a strong wear resistance.
Special bronze known as special bronze, high strength, hardness, corrosion-resistant chemical. Machining mechanical properties than Prominent. Pull into a seamless copper bronze, soft, strong wear resistance. The bronze seamless pipe heat exchanger and condenser can be used for low temperature piping, submarine transport tube. Manufacture of sheet metal, Rod, bar, pipe, cast parts. 62% to 68% in copper, plastic, manufacturing, such as pressure devices. Different types of alloying elements contained in the bronze, the bronze is divided into ordinary bronze and two special bronze. The mystery of bronze was unveiled. Pull up to a foot in the place, a look at all Shen person. Pressure processing of bronze called deformation bronze. room temperature, the organization of the ordinary bronze ordinary bronze is a copper-zinc binary alloy, the zinc content varied greatly, so the room temperature, the organization is also very different.
 Cu-Zn binary state diagram (Figure 6), the organization of bronze at room temperature, there are three: the microstructure of the zinc content of less than 35% of bronze, at room temperature by the single-phase alpha solid solution, referred to as α bronze; containing The zinc content in the range of 36% to 46% of bronze, the microstructure at room temperature by the (α + β) two-phase, known as the (α + β) Bronze (two bronze); zinc content of more than 46% ~ 50% of the bronze, the microstructure at room temperature only by the β phase, called β bronze. Six proportions of the alloy of copper with tin were recorded to cast bronze with different applications. single-phase bronze (from H96 to of H65) with good ductility and can withstand hot and cold processing, but the α single-phase bronze sculpture in temperature brittleness appears in forging and other thermal processing, the specific temperature range vary with the amount of Zn generally between 200 ~ 700 ℃.
