Two technologies of sintering municipal sewage sludge for manufacturing haydite ("wet process granulation-sintering" and "anhydration-sintering") were studied.
A white powder,coarse particles and mealiness ,hardly souble in acidic or alkaline solutions,with stable chemical property and good sintering performance.
The author introducd the electric equipment design of ore smelting eutecticum engineering of ore sintering plate, stated the problemes and the countermeasures.
Using dolomite and sinter magnesia clinker as a main material and added with alkali metal phosphate binder and additives,amagnesia-calcia coating material has been developed.
The effects of sintering parameters on the shear and bond strength of ceramet friction material were studied and its fracture morphology was observed and analyzed.
The color of the products is argent grey metallic shine, smooth, unknit. They mustn't be oxydic badly, lacking of sintering, over heating, delamination and cracking.
The obtained achievement in building material industry is studied, including sintering cement with substituting coal by cokeite and smelting rockwool with substituting coke by cokeite and so on.
The metal reflet glaze samples were prepared with the Huxian wheat-meal-stone accession 0%, 5%, 10% and 15% according to the traditional metal reflet glaze formula and then sintered at 950%.
For sinter with 25% and 50% MAC fines the iron oxides mainly consisted of hematite and magnetite, the bonding phase were mainly dicalcium silicate, glassiness, and a few amount of calcium ferrite.
