We offer riser cover for the straight one, necking downs and oblique riser. It is convenient for you to choose open riser or closed one. It has low density, high strength and good toughness, which suit for all kinds of black and non-ferrous casting. It can be set on the plate shape or embedded sand mold after modeling.
Heating mechanism: The exothermic Insulation Riser head has adopted good insulation material and high efficient exothermic. There are little quenching effect, once the liquid steel was pour into the riser head, the exothermic reaction will be activated, then the riser head will heat the liquid steel with it`s fever. After the reaction, the insulation material will ensure the coagulation time of the liquid steel. The best feeding efficient comes from the characters: Initial adiabatic, then fever, heat preservation for a long time in the end.

Wison Engineering (China) Co., Ltd. organized and completed the MTBE plant expansion and transformation project design, procurement and construction in an EM+PC (Design Management-Purchasing-General Contracting) method within a period of just 7 months. Achieve the standard of transportation. This project is the second MTBE installation completed by Wison Engineering for the contract of Guangzhou Petrochemical. Previously, in July 2008, Wison Engineering cooperated with Qilu Petrochemical Engineering Company in a general contracting manner and successfully built the first MTBE based on refinery carbon tetra as the raw material in China and the joint production of butene-1. In the past seven months, it has filled the technology gap in the domestic production of MTBE using refinery carbon 4 feedstock and the joint production of butene-1.
The energy expansion project of the MTBE (methyl tertiary butyl ether) plant contracted by Wison Engineering (China) Co., Ltd., a subsidiary of China Petroleum & Chemical Corporation (Guangzhou) Co., Ltd., has produced qualified products before reaching the design performance targets. This means that the passive situation in which Guangzhou Petrochemical Company MTBE relied on outsourcing was reversed.
