The MAN16/24 and MAN27/38 diesel engines are two series of diesel engines and generator sets launched by Zhonggao Diesel Heavy Industry Co., Ltd. this year. They can fully meet the international standards of IMO Tier I and Tier II emission requirements. Among them, the Tier II emission test of the MAN27/38 diesel engine is the first in the world.
Up to now, orders for hand-held boats and power plants for medium and high-tech diesel engines have reached 105, and production plans have been scheduled until June 2012. With the constant breakthrough of Zhonggong Diesel heavy industry marketing, the new orders will continue to increase. It is a foregone conclusion that the dual first machines will be favored by the market.
According to industry insiders, the investment in the production line of the Zhonggao new assembly line not only achieves a significant increase in production efficiency and production capacity, but also means that Zhonggao will leapfrog into two major market sectors, namely, the land and the sea.
First, the use of vacuum annealing furnace
This equipment is used for pre-vacuum nitrogen protection annealing heat treatment of carbon steel wire.
Second, the equipment composition
The well type resistance furnace mainly comprises: a furnace body, a furnace shell(tube), a furnace cover and a lifting mechanism, a furnace lining body, a heating element and a fixing device, and a furnace temperature control system.
