Smart use of <hr> but is it appropriate?

[Sylvant]

To mimic a menu/list icon i inserted 3 <hr>(horizontal lines) inside a <button>, but i wonder, how appropriate is that, regarding semantics mostly.

<button>
  <hr />
  <hr />
  <hr />
</button>

With some styling it makes the perfect icon

list button

Take a look at the definition of <hr> on MDN. I think it will answer your question.
