The utility model provides a tie package hoist is made to coil of strip, including hoist main part and safety rod, the upper end of hoist main part is provided with rings, the lower extreme of hoist main part is provided with down rings, the internal diameter of rings is greater than down the external diameter of safety rod, the length of safety rod is greater than beat the internal diameter of tie package. The wire rope who originally always continues to use has been replaced, the problem that has existed when having avoided using wire rope handling heavy object. When using above -mentioned hoist, passing from the column of playing tie package the hoist main part in hollow, then passing down rings with the safety rod, the both ends of guaranteeing the safety rod all contact with beating the lower bottom surface that the tie wrapped, then the couple of the equipment that will lift by crane and the linkage of hanging oneself connect, begin to lift by crane. This hoist convenient and fast ...

The invention relates to a pulverized coal burner, in particular to a rich-lean burner for uniform burning of concentrated-phase pulverized coal. The problems that when an existing rich-lean burner operates, nitrogen oxide emission is too high, and a nozzle is prone to coking are solved. An air-powder mixture forms a thick pulverized coal airflow and a thin pulverized coal airflow at the flaring under the action of the pulverized coal dense-thin separation body and the dense-thin airflow separation plate; concentrated-phase pulverized coal divides the nozzle into a plurality of nozzle units under the action of two bluff bodies arranged at the outlet of the cavity of the pulverized coal nozzle, and entrains and absorbs high-temperature flue gas in a large area on the whole airflow surface perpendicular to pulverized coal airflow, so that the inner part and the outer part of the pulverized coal airflow are ignited at the same time. The whole pulverized coal airflow is ignited at the air-coal ...

The invention discloses a cold rolling method of a hot rolling coiler, which comprises the following steps of: starting coiling quick-stop protection equipment after a normal coiling condition is not met, quickly starting shearing when the distance between the tail part of an intermediate billet and a flying shear is detected to be more than or equal to 5m in a finish rolling area with the thickness of strip steel less than 11mm, and completely rolling the strip steel less than 5m; a coiling start quick-stop finishing mill group with the thickness larger than or equal to 11 mm is in linkage start quick-stop roll gap quick opening, all strip steel is poured back to the middle billet push-out line to be processed, a coiling laminar flow pat is lifted to the highest position, three pinch rolls of a coiling machine are lifted to the maximum position, and a valve is closed to the zero position. And the head of the strip steel is straighter and is easy to coil by utilizing the downward pressing ...
