Common Faults and Treatment Methods in the Operation of Garbage Incinerator Grate
This chapter makes a deep analysis of the common faults and some minor problems in waste incinerators, thoroughly investigates the root causes of the problems, does not ignore the details that may occur at any point, and adopts a series of solutions according to the problems that arise, and puts forward numerous suggestions for operation technologies in the process of operation, so as to facilitate the normal operation of waste incinerators and obtain significant economic income without harming the environment and social development.

Plasma Transfer Arc (PTA) Applications
Abstract: Plasma arc welding (PTA) is a heat treatment process that applies wear and corrosion resistant layers to the surface of metallic materials. A high-energy plasma arc melts the surface of the base material. At the same time, powdered filler material is introduced into the arc and melted. During the polymerisation process, a substance-to-substance bond is formed between the filler material and the base material.

Application of High Temperature Sand Coating on Small and Medium Cast Steel Parts
Abstract: According to the characteristics of film sand, this paper presents the quality problems encountered in the steel casting sand produced by the author's company, analyzes the causes of them, and adopts various formulas and processes for different practical situations so that steel castings can be produced that meet the requirements of the film sand process, which is especially suitable for investment casting of steel castings.

Application of Cladding Sand in Casting
Clad sand casting in the foundry field has a fairly long history, casting production is also quite large; but the use of clad sand casting production of precision cast steel parts face many problems: sticky sand (scarring), cold segregation, porosity. How to solve these problems to be further explored.

A Method to Solve the Porosity of Investment Casting
Abstract: Single-gate, top-injection flow casting, applying repeated use of medium-temperature mould material, using secondary dewaxing, to ensure that all the wax in the shell is removed, to prevent intrusive gases from being produced in the casting.
Keywords: Medium temperature mould material, secondary dewaxing, air holes.

Site Mapping of Shanghai Laogang Waste Incineration Plant
At the invitation of the customer, we sent our technical experts to Shanghai Laogang Waste Incineration Plant to carry out full-size mapping and chemical composition analysis of the grates, grate beams, partition castings and other fittings. According to the wear and tear situation of the grate and the maintenance situation of the parts in the furnace, we provide optimised solutions to the site staff.
