In order to design reasonably the wind\'s pressure of the ironore sinter machine of the iron and steel enterprise,the cooling resistance of the iron-ore sinter machine,which is a basic parameter of the wind pressure,was theoretically deduced,and the machematical models about resistants\' calculation was established,and the calculation program was designed based on C++ Builder.

Aiming at decreasing the heat environment of platform from piston wind by using cooling damping wind to control piston wind.

The processing characteristics and calculation methods of parameters of watersoaking cooling bed were introducedThe shortage of cooling ability of original cooling bed can be resolved by this type of cooling bed,and the good effects are obtained

This paper analyzed heat transfer process in quenching and discussed the distinction between cooling power and hardenability of quenchant.

The results show that the cooling power variation of water caused by temperatures is obviously stronger than that caused by flow rates;The cooling characteristic.

Correction of water temperature difference for evaluation of cooling capacity of standard cooling towers;

Through improving disposition way of cooler and construction of thermostat, it was realized that the loader cooling capacity is auto-adjustable to adapt to its radiating need, so it s running function is improved.

The differences between ordinary quenching oil and mechanical quenching oil were compared in detail, such as the temperature under the maximum cooling rate, cooling capacity, cooling characteristic and the cooling rate between 300℃ and 200 ℃, the physical chemical indicators, the safety in use, environmental pollution, the worklife, economic effect, quenching quality and so on.
