Abstract

The invention discloses it is a kind of for magnesium alloy leading screw casting machine lubrication miscella boil technique, by weigh raw material, heating boil, mix, be sufficiently mixed after obtain compound lard；Technological operation is convenient and simple, it is to avoid ultra high temperature lubricating grease is not easy to apply at normal temperatures, need to only smear once, and the process for boiling is also very convenient, stickiness and heat-resisting quantity are effectively unified；The usage amount of lubricating oil is greatly reduced, cost has been saved.

Description

A kind of miscella for magnesium alloy leading screw casting machine lubrication boils technique

Technical field

Technical field is boiled the invention belongs to lubricating oil, and in particular to a kind of miscella for magnesium alloy leading screw casting machine lubrication is endured Technique processed.

Background technology

At present, the semi-continuous casting of magnesium alloy possesses continuity of production process is strong, and yield rate, productivity ratio are high, and labour intensity is small etc. Series of advantages, semicontinuous casting machine can raise labour productivity, and improve slab quality, reduce labour intensity；Therefore, it is this Molding mode will enjoy great popularity in following section bar field of magnesium alloy.

Conticaster needs periodically to carry out care and maintenance, the crucial lubrication for being that leading screw mould is maintained to obtain, from conticaster From the point of view of condition of work, cunning fat is in high temperature, heavy load, Qiang Shuilin, the environment of the slow-speed of revolution, and most of using concentration profit Sliding, the ultra high temperature lubricating grease that the same industry is mostly used has excellent heat-resisting quantity and inoxidizability, can avoid being transported in high temperature Grease is lost in during row；With excellent extreme pressure, abrasion resistance and bearing capacity, can long-acting reduction gear wear；With stronger Adhesion, can overcome rotating speed centrifugal force high, be difficult to be got rid of in high speed.

But, ultra high temperature lubricating grease is at normal temperatures solid-state, is not easily accessed in mould to oil when being smeared in leading screw mould, is led to Often need to smear 2-3 times, serious waste individually boils ultra high temperature lubricating grease, oil is too thick, and is easy to solidify again, such as Fruit uses antiwear hydraulic oil, and non-refractory；Therefore, how effectively two kinds of oil mixing to be boiled, the oil for boiling out both may be used With high temperature resistant, viscosity can be reduced again, the smearing for being easy to casting machine is a difficult problem for being badly in need of solving at present.

The content of the invention

There is grease present invention aim to address prior art and smear inconvenience and the serious technical problem of waste, there is provided Yi Zhongyong Technique is boiled in the miscella of magnesium alloy leading screw casting machine lubrication, to overcome the deficiencies in the prior art.

To achieve these goals, the present invention is achieved through the following technical solutions：

A kind of miscella for magnesium alloy leading screw casting machine lubrication boils technique, and it comprises the following steps：

Step 1）Weigh raw material：Weigh ultra high temperature lubricating grease 2-2.5kg standby；

Step 2）Heating is boiled：By step 1）The grease for weighing is placed in crucible and is heated to 80-100 DEG C and dissolves, in heating process It is stirred continuously；

Step 3）：With the temperature of thermocouple measurement oil body at 80-100 DEG C, the hydraulic oil of 1.5kg-2kg is slowly added to, added During be stirred continuously, until after being sufficiently mixed, stop stirring；

Step 4）：Continue to heat and be sufficiently stirred for, stop adding during with the temperature of thermocouple measurement oil body between 120 DEG C -150 DEG C Heat, after naturally cool to normal temperature after, obtain final product.

The beneficial effects of the invention are as follows：Technological operation is convenient and simple, it is to avoid ultra high temperature lubricating grease is at normal temperatures difficult to apply Smear, need to only smear once, the process for boiling is also very convenient, and stickiness and heat-resisting quantity are effectively unified；Significantly The usage amount of lubricating oil is reduced, cost has been saved.

Specific embodiment

Hereinafter further explanation will be made to the present invention using specific embodiment, but it is not intended as to present invention innovation essence The limitation of god.

Embodiment 1

A kind of miscella for magnesium alloy leading screw casting machine lubrication of the present invention boils technique, and it comprises the following steps：

Step 1）Weigh raw material：Weigh ultra high temperature lubricating grease 2.5kg standby；

Step 2）Heating is boiled：By step 1）The grease for weighing is placed in crucible and is heated to 100 DEG C and dissolves, in heating process constantly Stirring；

Step 3）：With the temperature of thermocouple measurement oil body at 100 DEG C, the hydraulic oil of 2kg is slowly added to, in adition process constantly Stirring, until after being sufficiently mixed, stopping stirring；

Step 4）：Continue to heat and be sufficiently stirred for, heating is stopped at 100 DEG C with the temperature of thermocouple measurement oil body, treat nature After being cooled to normal temperature, obtain final product.

Embodiment 2

Embodiment 1

A kind of miscella for magnesium alloy leading screw casting machine lubrication of the present invention boils technique, and it comprises the following steps：

Step 1）Weigh raw material：Weigh ultra high temperature lubricating grease 2kg standby；

Step 2）Heating is boiled：By step 1）The grease for weighing is placed in crucible and is heated to 80 DEG C and dissolves, in heating process constantly Stirring；

Step 3）：With the temperature of thermocouple measurement oil body at 80 DEG C, the hydraulic oil of 1.5kg is slowly added to, in adition process not Disconnected stirring, until after being sufficiently mixed, stopping stirring；

Step 4）：Continue to heat and be sufficiently stirred for, heating is stopped at 120 DEG C with the temperature of thermocouple measurement oil body, treat nature After being cooled to normal temperature, obtain final product.

Present invention process is easy to operate simple, it is to avoid ultra high temperature lubricating grease is not easy to apply at normal temperatures, only need to smear one Secondary, the process for boiling is also very convenient, and stickiness and heat-resisting quantity are effectively unified；Greatly reduce lubricating oil Usage amount, has saved cost.
