Discussion on Application of Hot Aluminous Weldment Technology in Metallurgical Crane Tracks;

Study to the Approach to Transfiguration and Repair for Crane Girder;

In smelting process,large amount of cables of crane working in hot environment are likely to reduce its useful-life that can't be known.

The article has introduced the layout of roadway and equipment in charging chamber and demonstrated the applicable prospect of traveling crane.

briefly introduces the characteristics,types and composition of the traveling crane air-condition;analyzes the thermal environment both in and outside the traveling crane s electrical rooms,which is based on the data from a field survey in an iron and steel phant.

This thesis de-scribes the realization technologies of the electrical control system i n the industrial traveling crane whi ch has been designed and made all by ours elves.

The paper introduces formerly questions about operational mod of travelling cranes of main and auxiliary wells, advances the frequency conversion reform,gives the system-map of the main-loop, generalizes the main design characteristic and effect after reform.

24 travelling crane in the Steelworks gave rise to bigger influences for safe production in the plant.

With the development of efficient and the demand of lager scale and higher velocity, the travelling crane needs to be more intelligent with high technology.

In automatic production in an immersion production line, the automatic stable running of bridge crane is critical.

This article is mainly introduced Guixi Smelter Factory,Smelter workshop bridge crane s weight measurement and wireless remote control scheduling system.

Through the analysis of the application of " off- normal operation entry safety monitor unit" in overhead crane, this paper probes into the functions and limitations of the monitor unit from the angle of overhead crane drivers operation, analyzes the shortages existing in the graphic structure of original station, and puts forward a concept of improving the grahpic structure of original station.

Based on analyzing common faults of charging overhead crane and making improvement, work efficiency of overhead crane has been increased and normal production is ensured.

Based on this, the traffic property of the vehicles in tunnel group was obtained through analyzing the data.

Degradation of ZDDP in CD/SF 5W/30 engine oil during field test investigated by ~(31)P-NMR spectroscopy;

Through blending different base oils and VIIs,the field test of self-developed CF-4(15W/40) diesel engine oils for over 20,000 km was carried out with Volvo and Mercedes-Benz heavy-duty trucks in order to investigate the effect of degradation of engine oils on its performance.

The field tests in sixteen vehicles of four types proved that the performances of above oil are excellent and corresponding to the foreign products of a kind.

Virtual simulation test of perception factors for operating speed;
