This utility model relates to a hydrogen peroxide quartz lamp burner, belonging to the field of quartz product manufacturing equipment. The burner consists of five parts: a lamp cover, a lamp holder, an oxygen pipe, a hydrogen pipe, and a feeding pipe. The main feeding pipe is divided into four branch feeding pipes, which are evenly distributed circumferentially through the lamp cover and extend into the central interlayer formed by the fusion of the lamp cover and the lamp holder, forming a feeding channel. Quartz powder can slide along the surface of the interlayer to the molten pool for easy melting. Three oxygen pipes and two hydrogen pipes are connected to the outside of the lamp cover, and the hydrogen and oxygen are separated by the lamp holder to prevent them from mixing and exploding inside the quartz lamp. The two hydrogen pipes are fused to the lamp cover and connect to the central interlayer; the three oxygen pipes penetrate the lamp cover and are fused to the lamp holder. A sieve plate is placed inside the lamp holder, and at its lower part, wick tubes of different levels, each with the same focal point, are obliquely welded in a ring array, guiding the flow of the mixed gas to ensure complete combustion, increasing the burner's operating temperature, and thus improving the quality of silicon dioxide melting.

The application discloses a composite crucible for smelting aluminum-lithium alloy and a preparation method thereof. The composite crucible is composed of an outer heat-resistant cast steel layer, a middle carbon fiber felt layer and an inner silicon carbide ceramic layer. The heat-resistant cast steel is one of ZG40Cr24Si2, ZG50Cr28Ni48W5 and ZG35Cr24Ni7NRE. The middle layer is a carbon fiber felt with a porosity of 30-70% prepared from mesophase pitch-based carbon fibers. The silicon carbide ceramic layer is composed of 85-90% silicon carbide, 5-8% SiO2 and 2-10% mullite. The preparation process of the crucible is simple. The main body of the crucible does not react with lithium, thereby ensuring the quality of the melt. The multi-layer structure makes it easier to replace and repair the damaged crucible, thereby prolonging the service life of the crucible. Meanwhile, the crucible is convenient to transfer and will not crack during the smelting process.
