Core manufacturing method by using oil-sand

Abstract

The invention discloses a core manufacturing method by using oil-sand. The method comprises the steps that: raw materials such as asphalt, oil, mineral-rich clay, and water are selected; 10-12% of asphalt, 80-85% of sand and clay, and 3-5% of water are mixed, such that oil-sand is prepared; the oil-sand is placed in a mould, and is beaten by using a hammer; while beating, oil-sand is continuously added into the mould, such that the mould is filled with the oil-sand; the integral body of the oil-sand core in the mould is fetched; and at least one hole is punched on the oil-sand core; the oil-sand core is dried by baking under a temperature of 170 DEG C in a drying electric furnace, and is fetched after 4h. The method provided by the invention is convenient, time-saving, and effort-saving. With the method, working efficiency can be improved.

Description

Technical field: [0001] The invention relates to a method for making cores from oil sand. Background technique: [0002] Today, oil sand refers to sedimentary sand rich in natural bitumen, oil sand bituminous oil with high density, high viscosity, high carbon-hydrogen ratio and high metal content, because the oil sand core has no strength before baking, the sand core is easy to produce Deformation, so it is necessary to put the oil sand core into the drying electric furnace. The general drying temperature cannot meet the requirements, resulting in poor drying quality and affecting the overall efficiency. Invention content: [0003] The object of the present invention is to overcome the above disadvantages and provide a method for making cores from oil sands that is easy to operate, saves time and effort, and improves work efficiency. [0004] The purpose of the present invention is achieved through the following technical solutions: a method for making cores from oil sand...
