The invention provides super-strong high-phosphorus boron cast iron. The super-strong high-phosphorus boron cast iron is made from molten iron and ingredients and is characterized in that the ingredients comprise the following raw materials in percentage by weight: 2.5-4% of C, 0-0.1% of S, 1.5-2.5% of Si, 0.2-0.4% of P, 0.05-0.5% of Cr, 0.5-1% of Mn and 0.05-0.2% of B. The super-strong high-phosphorus boron cast iron has the advantages that the abrasive resistance is good; the complete machine is durable in use and long in life; the economic benefit is increased; in the meantime, the energy consumption is low and the stability is good; virtuous circle is formed among components; the energy is saved and the emission is reduced; the boron cast iron is suitable for cutting machining; the machining indexes achieve the design standard; and the best adaptation performance is shown between the boron cast iron and a piston ring.
Description
technical field [0001] The invention belongs to the field of cast iron, in particular to a super-strong high-phosphorus-boron cast iron. Background technique [0002] The cast iron of the cylinder block of the existing automobile air compressor is either too hard and easy to damage, or too soft and not wear-resistant, which affects the service life of the whole machine, high energy consumption, and poor stability. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a super-strong high-phosphorus-boron cast iron. [0004] A super-strength high-phosphorus-boron cast iron prepared from molten iron and a formula seasoning, characterized in that the weight percentage of each raw material in the formula seasoning to the total weight of the molten iron and the formula seasoning is: C: 2.5-4%; S: 0-0.1%; Si: 1.5-2.5%; P: 0.2-0.4%; Cr: 0.05-0.5%; Mn: 0.5-1%; B: 0.05-0.2%. [0005] The super-strong high-phosphorus-boron...
