Research and Practice of Technological Processes and Facilities of Refractory Fibre Manufactured in Resistance-heated Furnace

On the principle of correlation between the fluidmovement and the viscosity, the flow rate of the meltthrough the nozzle is determined by the viscosity of alumini-um silicate melt which can be controlled to reach the goalof the continuous melting and blowing in the resistance fur-nace and to prolone the furnace campaign. After the spe-cial type of N-L composite nozzle was applied to the fur-     

Research and Practice of Technological Processes and Faciites of Refractory Fibre Manufactured in Resistane-heated Furnace

On the rinciple of correlation between the fluid movement and the visocsity,the flow rate of the melt through the nozzle is determined by the viscosity of aluminium silicate melt which can be controlled to reach the goal of the conntinumous melting and blowing in the resistance furnace and to prolong the furnac capaign,After the special type of N-L composite nozzle was applid to the furnace,per ton refractory fibre costs is reduced by 579 Yuan and the producivity increases by 80%,The effect of energy saving is striking,Alter the innovation of continuous melting and blowing resistance furnace production line for the aluminium silicate fibre,annual production cost of 580,000 Yuan has been saved the furnace campaign life increases by 5-8 times and the consistency and reliability of product quality have been greatly improved.

Development and Applicatio of Refractories for Self—heating opper—smelting Furnace

The development and application of high quality refractories for self-heating copper-smelting furnae (SHCSF),which adopts the most advanced copper-smelting process in the world,has been introduced in this paper. The service life of the furnace has been increased from one and a half months to around 20 months by using high quality refractiories and improving the mason method.     

Combining Mutualistic Yeast and Pathogenic Virus — A Novel Method for Codling Moth Control

The combination of a pathogenic virus and mutualistic yeasts isolated from larvae of codling moth Cydia pomonella is proposed as a novel insect control technique. Apples were treated with codling moth granulovirus (CpGV) and either one of three yeasts, Metschnikowia pulcherrima, Cryptococcus tephrensis, or Aureobasidium pullulans. The combination of yeasts with CpGV significantly increased mortality of neonate codling moth larvae, compared with CpGV alone. The three yeasts were equally efficient in enhancing the activity of CpGV. The addition of brown cane sugar to yeast further increased larval mortality and the protection of fruit against larvae. In comparison, without yeast, the addition of sugar to CpGV did not produce a significant effect. A field trial confirmed that fruit injury and larval survival were significantly reduced when apple trees were sprayed with CpGV, M. pulcherrima, and sugar. We have shown earlier that mutualistic yeasts are an essential part of codling moth larval diet. The finding that yeast also enhances larval ingestion of an insect-pathogenic virus is an opportunity for the development of a novel plant protection technique. We expect the combination of yeasts and insect pathogens to essentially contribute to future insect management.     

Physical Properties and Hydration Resistance of CeO2—and CeO2／Fe2O3—Bearing Dolomite Refractory Products

Dolomite refractory products with excellent hydration resistance have been produced by using CeO2-and CeO2/Fe2O3-bearing dolomite clinkers,Their physical properties as well as hydration resistance have been investigated,The addition of CeO2 has little harmful effect on the high temperature properties of dolomite refractory products such as hot MOR and slag resistance,And the shelf lives of the dolomite refractory products containing CeO2 and CeO2/Fe2O3 additions at the same condition are two times that of the common dolomite refractory produt.The dolomite refractory product containing CeO2/Fe2O3 combination possesses the best hydration resistance,but gives poor slag resistance.
